TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 662,230, datedNovember 2.0, 1900.

Application filed August 16, 1900. Serial No. 27,103. (No model.)

To all whom it nuty concern.-

Be it known that I, CHARLES L. FENToN, a citizen of the United States,and a resident of West Winfield, in the county of Herkimer and State ofNew York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to ribbon-spools of type-writing and othermachines; and its object is to provide means for firmly attaching theend of the ribbon to the spool and readily releasing it therefrom whendesired without the necessity of soiling the fingers in handling theribbon.

To this end my invention consists, primarily, in the combination with aribbon-spool of a device for clamping the ribbon upon the core of thespool and a finger-piece arranged outside of the spool-flange forraising the clamp and releasing the ribbon therefrom.

My invention further consists in certain features of construction andcombinations of devices, all as will be more fully hereinafter setforth, and particularly pointed out in the concluding claims.

In the accompanying drawings, Figure 1 is a plan of a ribbon-spool, suchas is used in the Remington N0. 6 type-writing machines, showing myimprovements applied thereto, the ribbon-clasp being broken away todisclose the construction therebeneath. Fig. 2 is a rear elevation ofthe spool, the rear flange being partly broken away and the core andother parts being shown in section. Fig. 3 is a side elevation of thespool, the ribbon attached thereto being indicated by dotted lines. Fig.4: is a sectional front elevation of the spool with the ribbon attached.Fig. 5 is an elevation of a modified clamp-releasing device, and Fig. 6is a front elevation of the spool.

Throughout the several views similar parts are designated by similarnumerals of reference.

The front spool-flange is designated as 1, the rear flange as 2, and thewooden core as 3. As usual, the core is recessed at 4 and the rearflange perforated at5 in line with said recess to permit the entrance ofthe weighted arm which forms part of the automatic ribbon-re- Versingmechanism in said type-writing machine. The flanges are secured to theends of the core by screws 6, and the whole structure is bored axiallyat 7 to receive the usual spool-shaft.

I provide a clamp consisting of a leaf-spring 8, curved to conform tothe general curvature of the spool-core and secured at one longitudinaledge to the latter by means of screws 9. The spring preferably coversabout onefourth of the periphery of the spool-core, and its freelongitudinal edge is provided with a series of inwardlydirected teeth10. The teeth or serrations engage the ribbon fabric and clamp itagainst the core; but so far as certain features of my invention areconcerned the serrations are not essential so long as the ribbon isproperly clamped or held. If desired, a peripheral recess 11 may be out1011- gitudinally of the spool-core in position to cooperate with theteeth 10 to hold the ribbon.

Means are provided for enabling the operator to force the free end ofthe spring-clamp away from the spool-core, so as to permitthe insertionor removal of the end of the ribbon. I prefer to use a bail extendingbetween and pivoted in the spool-flanges at 12 and lying beneath theclamp 8 or between said clamp and the spool-core, the latter being cutaway at 13 to afford room for the bail. The forwardly-projecting end oraxis of the latter is provided with a button 14, whereby the bail may berotated upon its pivots 12. During this movement the arms 15 of the bailvibrate and cause the cross-bar 16 of the bail to engage the undersurface of the clamp 8 and force the latter outwardly and away from thespool-core, as indicated at Fig. 2, whereby the ribbon is released andmay be withdrawn from the spool. When it is desired to insert anotherribbon, the parts are again moved to the Fig. 2 position and the end ofthe ribbon is dropped between the spool-core and the clamp, whereuponthe button 14. is released and the spring 8 snaps into working position,as indicated at Fig. 4, doubling the ribbon down in the recess 11 andfirmly holding it there.

In the modification shown at Fig.5 the button 14 is omitted and theprojecting end or shaft of the bail is bent at 17, so that the free end18 thereof extends parallel with the spoolflange and close thereto, thusforming a convcnient lever for operating the bail to release the clampand occupying less room in the machine than is taken by the projectingbutton 14.

It will be seen that by means of the foregoing construction the ribbon(designated as 19) may be instantly detached from or reattached to thespool and that by the provision of a clamp-raising button orfinger-piece outside of the spool-flange said clamp may be openedreadily and without liability of soiling the fingers. It will also beseen that the device is positive in action, inexpensive to manufacture,and readily applicable to existing machines.

I regard the provision of an outside fingerpiece as of specialimportance, and while I have illustrated but two constructions of saidfinger-piece, yet I do not consider that the invention is limitedthereto or to any particular mechanism operated by said finger-piece, asthe gist of the invention resides in the combination, with aribbon-clamp arranged within the spool or at the spool-core, of alifting device extending from said clamp to a point outside of thespool. It is not essential in all cases that the releasing devices shallextend through the spool-flange, as it may be otherwise arranged to beconvenient of access and to avoid the necessity of bringing the fingersof the operator into contact with either the ribbon or any part that hasbeen smeared with ink therefrom. Many'other changes in details ofconstruction and arrangement may be made within the scope of theinvention.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a ribbon-spool having a flange, the combination with aribbon-clamp arranged upon one side of said flange, of a finger-piecearranged at the other side of said flange and connected to said clampfor raising the latter.

2. In a ribbon-spool having a flange, the combination with aribbon-clamp arranged upon one side of said flange, of a fingenpieceextending from said clamp through said flange.

3. In a ribbon-spool comprising a pair of flanges, the combination witha ribbon-clamp arranged between said flanges, of a fingerpieee arrangedat one end of the spool outside of the flange and connected to saidclamp for raising the latter.

4. In a ribbon-spool, the combination of a core, a flange, a springarranged upon one side of said flange for clamping the'ribbon to thecore, and a finger-piece arranged upon the other side of said flange andconnected to said spring.

5. In a ribbon-spool, the combination of a pair of flanges united by acore, a spring secured upon said core for clamping the end of the ribbonthereto, and a finger-piece connected to said spring and extendingthrough one of said flanges.

6. In a ribbon-spool, the combination with a ribbon-clamping spring, ofa crank 15 provided with a finger-piece and constructed and arranged toact upon said spring and cause the latter to release the ribbon.

7. In a ribbon-spool comprising a pair of flanges and a core, thecombination of a ribbon clamping spring, a bail arranged between andpivoted in said flanges and constructed to engage said spring and causeit to release the ribbon, and a finger-piece for said bail.

8. In a ribbon-spool comprising a pair of flanges and a core, thecombination of a ribbon-clamp spring, a bail arranged between andpivoted in said flanges and constructed to engage said spring and causeit to release the ribbon, and a finger-piece for said bail, saidfinger-piece being in the form of a lever which extends from the axis ofsaid bail alongside of the spool-flange and close thereto.

9. In a ribbon-spool, the combination with a pair of flanges and a core,of a spring over lying said core and secured thereto and constructed atits free end to clamp the end of the ribbon to said core, a bail lyingbetween said spring and said core and pivotally mounted in saidspool-flanges, and a finger-piece for said bail.

10. In a ribbon-spool, the combination with a pair of flanges and acore, of a spring overlying said core and secured thereto andconstructed atits free end to clamp the end of the ribbon to said core,a bail lying between said spring and said core and pivotally mounted insaid spool-flanges, and a finger-piece for said bail, said finger-piecebeing arranged outside one of said flanges and upon a part of the bailwhich extends through the flange.

11. In a ribbon-spool, the combination with a pair of flanges and acore, ofa ribbon-clamp overlying said core, and a bail arranged betweensaid clamp and said core and pivotally mounted at its ends in saidspool-flanges, one end of said bail being prolonged and bent to form afinger-lever for turning said bail to release said clamp.
